Framing Calculator

Your details

Total length of the wall measured from outside edge to outside edge.
ft
Floor-to-ceiling height. Standard stud walls are 8 ft, 9 ft or 10 ft. Height affects stud length and whether fire blocking is required.
ft
On-center distance between studs. 16" is the standard residential code minimum; 24" (advanced framing) uses ~33% fewer studs and improves insulation continuity.
Interior walls use 2x4 lumber and carry no structural load. Exterior load-bearing walls need larger headers over openings. 2x6 exterior walls allow more insulation depth.
2-stud corners (California corners) save lumber and improve insulation. Traditional framing uses 3 studs at each corner.
Rough-opening width of a single door or window. Leave at 0 for a wall with no openings. The calculator adds king studs, jack studs, a correctly sized header and cripples automatically.
in
Rough-opening height. Typical interior door: 80 in. Window: 48-60 in.

When enabled, the calculator estimates 4x8 sheets of OSB or plywood sheathing for the wall face.
Add a percentage to account for cuts, defects and errors. Industry standard is 10-15%.

24 studs needed for this 16 ft wall.

  • You need 24 studs total at 16-inch on-center spacing for a 16 ft wall.
  • The opening adds king studs, jack studs and cripples. Header size per IRC: 2x4 flat or 2x6 on edge.
  • You will need 5 sheets of 4x8 sheathing to cover the wall face.
  • Estimated material cost is approximately $420.00 before tax and delivery.

Next stepConsider 24-inch O.C. spacing (advanced framing) to reduce lumber by roughly 33% and improve insulation continuity without sacrificing structural performance in most single-story applications.
